Proyectil para armas de fuegoProjectile for firearms

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Es conocida en el actual estado de la técnica la utilización de materiales compuestos para la fabricación de balas o proyectiles para armas de fuego. Estos materiales, al ser más ligeros que los materiales convencionales, hace que el proyectil se desplace a una velocidad más alta y/o que gire mucho más rápido que los proyectiles convencionales. Este aumento de la velocidad de desplazamiento y/o de giro causa una variación en la forma y en la capacidad del proyectil de alterar el objetivo en el que impacta. Por ello, existen distintos diseños de proyectil que tienen la intención de conseguir un mayor rendimiento o diferentes efectos a la hora de impactar, como por ejemplo los mostrados en las patentes US9829293 y US10126105.The use of composite materials for the manufacture of bullets or projectiles for firearms is known in the current state of the art. These materials, being lighter than conventional materials, causes the projectile to move at a higher speed and / or to rotate much faster than conventional projectiles. This increase in the speed of movement and / or rotation causes a variation in the shape and ability of the projectile to alter the target it hits. Therefore, there are different projectile designs that are intended to achieve greater performance or different impact effects, such as those shown in patents US9829293 and US10126105.

En ciertos casos en que el objetivo de impacto es un tejido blando, es deseable que la penetración sea menos profunda y que el objetivo absorba la mayor cantidad de la energía cinética impartida al proyectil en el proceso de disparo. La presente invención contribuye a aportar una solución a la existente necesidad.In certain cases where the impact target is a soft tissue, it is desirable that the penetration be shallower and that the target absorb the greatest amount of kinetic energy imparted to the projectile in the firing process. The present invention contributes to provide a solution to the existing need.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

El presente proyectil para armas de fuego corresponde a un proyectil definido por una porción de impacto en forma ojival y una porción posterior en forma cilíndrica, donde ambas porciones definen un eje longitudinal común. Dicha porción ojival comprende tres hendiduras, situadas a una misma longitud respecto al eje longitudinal y perimetralmente equidistantes, las cuales están definidas por dos superficies simétricas entre sí. Sendas superficies se intersectan en unas respectivas crestas, las cuales presentan una menor profundidad que el fondo de sendas superficies.The present firearm projectile corresponds to a projectile defined by an ogival shaped impact portion and a cylindrical shaped rear portion, where both portions define a common longitudinal axis. Said ogival portion comprises three slits, located at the same length with respect to the longitudinal axis and perimetrically equidistant, which are defined by two surfaces symmetrical with each other. Both surfaces intersect at respective ridges, which have a shallower depth than the bottom of each surface.

Gracias a esta configuración, cuando el proyectil penetra en un tejido blando, se aumenta el efecto de frenado, haciendo que la energía disipada en el objetivo de impacto sea mayor. Thanks to this configuration, when the projectile penetrates a soft tissue, the braking effect is increased, making the energy dissipated in the impact target greater.

En una realización preferente, las mencionadas crestas forman una curva cóncava. Gracias a ello, el proyectil recibe un mayor efecto de frenado hacia el final de la porción de impacto. In a preferred embodiment, said ridges form a concave curve. As a result, the projectile receives a greater braking effect towards the end of the impact portion.

En otra posible realización, las superficies también presentan concavidad desde el punto de vista de todos sus planos normales al eje longitudinal, lo que produce aún un mayor efecto de frenado. Preferiblemente, cada superficie a la vez se divide en dos caras, cuyas intersecciones tienen forma de V desde el punto de vista de sus planos normales al eje longitudinal. De esta forma, se consigue todavía un mayor efecto de frenado.In another possible embodiment, the surfaces also have concavity from the point of view of all their normal planes to the longitudinal axis, which produces an even greater braking effect. Preferably, each surface at the same time is divided into two faces, the intersections of which are V-shaped from the point of view of their normal planes to the longitudinal axis. In this way, an even greater braking effect is achieved.

De forma opcional, la parte de las intersecciones más cercana a la porción posterior se aleja del respectivo plano medio longitudinal a medida que se encuentra más cerca de la porción posterior. De esta forma, el recorrido que perciben los tejidos del objetivo a través del proyectil es mayor, aumentando así el efecto de frenado.Optionally, the part of the intersections closest to the posterior portion moves away from the respective longitudinal median plane as it is closer to the posterior portion. In this way, the path perceived by the target tissues through the projectile is greater, thus increasing the braking effect.

Respecto a la proporción que deben ocupar las superficies de las hendiduras respecto a la superficie de impacto, preferentemente se define que la superficie proyectada de las hendiduras en un plano normal al eje longitudinal L) es entre un 30% y un 60% del total de la superficie proyectada del diámetro del proyectil.Regarding the proportion that the surfaces of the grooves must occupy with respect to the impact surface, it is preferably defined that the projected surface of the grooves in a plane normal to the longitudinal axis L) is between 30% and 60% of the total the projected surface of the diameter of the projectile.

Como realización preferente, este tipo de proyectil comprende o está fabricado por una mezcla de partículas metálicas y material de matriz polimérica.As a preferred embodiment, this type of projectile comprises or is made of a mixture of metallic particles and polymer matrix material.

En resumen, se ha desarrollado un proyectil capaz de transferir su energía cinética de una forma óptima a un objetivo de impacto formado por tejido blando.In summary, a projectile capable of optimally transferring its kinetic energy to a soft tissue impact target has been developed.

Estas y otras características y ventajas de proyectil objeto de la presente invención resultarán evidentes a partir de la descripción de una realización preferida, pero no exclusiva, que se ilustra a modo de ejemplo no limitativo en los dibujos que se acompañan.These and other characteristics and advantages of the projectile object of the present invention will become apparent from the description of a preferred, but not exclusive, embodiment that is illustrated by way of non-limiting example in the accompanying drawings.

DESCRIPCIÓN DE UNA REALIZACIÓN PREFERENTEDESCRIPTION OF A PREFERRED EMBODIMENT

Tal y como se muestra en las figuras 1 y 2, la realización preferente de la presente invención se compone de un proyectil definido por una porción de impacto (1) en forma ojival y una porción posterior (2) en forma cilíndrica, donde ambas porciones (1, 2) definen un eje longitudinal común. Dicha porción ojival (1) comprende tres hendiduras (11), situadas a una misma longitud respecto al eje longitudinal y perimetralmente equidistantes, las cuales están definidas por dos superficies (11a, 11b) simétricas entre sí. Sendas superficies (11a, 11b) se intersectan en unas respectivas crestas (12), las cuales presentan una menor profundidad que el fondo de sendas superficies (11a, 11b). Evidentemente, por el hecho de que las mencionadas superficies deben ser simétricas, las crestas (12) son coplanarias con el eje longitudinal del proyectil.As shown in Figures 1 and 2, the preferred embodiment of the present invention consists of a projectile defined by an impact portion (1) in an ogival shape and a posterior portion (2) in a cylindrical shape, where both portions (1, 2) define a common longitudinal axis. Said ogival portion (1) comprises three slits (11), located at the same length with respect to the longitudinal axis and perimetrically equidistant, which are defined by two surfaces (11a, 11b) symmetrical with each other. Both surfaces (11a, 11b) intersect at respective ridges (12), which have a shallower depth than the bottom of each surface (11a, 11b). Obviously, due to the fact that the mentioned surfaces must be symmetrical, the ridges (12) are coplanar with the longitudinal axis of the projectile.

En esta realización preferente, las mencionadas crestas (12) forman una curva cóncava. Así su vez, cada superficie (11a, 11b) se divide en dos caras cóncavas, cuyas intersecciones (13a, 13b) tienen forma de V desde el punto de vista de sus planos normales al eje longitudinal.In this preferred embodiment, said ridges (12) form a concave curve. Thus, in turn, each surface (11a, 11b) is divided into two concave faces, whose intersections (13a, 13b) are V-shaped from the point of view of their normal planes to the longitudinal axis.

Como se puede apreciar en la figura 2 de esta realización de ejemplo, la parte de las intersecciones (13a, 13b) más cercana a la porción posterior (2) se aleja del respectivo plano medio longitudinal (P) a medida que se encuentra más cerca de la porción posterior (2).As can be seen in figure 2 of this example embodiment, the part of the intersections (13a, 13b) closest to the rear portion (2) moves away from the respective longitudinal median plane (P) as it is closer. of the posterior portion (2).

En la figura 3 se muestra la superficie proyectada (S) de las hendiduras (11) en un plano normal al eje longitudinal, así como la superficie proyectada del diámetro del proyectil. En esta realización de ejemplo, la superficie proyectada (S) de las hendiduras corresponde a un 40% del total de la superficie proyectada del diámetro del proyectil. Figure 3 shows the projected surface (S) of the slits (11) in a plane normal to the longitudinal axis, as well as the projected surface with the diameter of the projectile. In this example embodiment, the projected surface (S) of the slits corresponds to 40% of the total projected surface of the diameter of the projectile.
